Summary: Improvements to Autoscaling in Apache Stratos
Key: STRATOS-488
URL: https://issues.apache.org/jira/browse/STRATOS-488
Project: Stratos
Issue Type: Improvement
Components: Autoscaler
Reporter: Lahiru Sandaruwan
You can find some details about autoscaling from [1] and [2].
1. Improve Autoscaling to predict the number of instances required in the next
time interval.
Currently we predict the load for next time interval. Then we use a threshold
to decide on scale up or down. Factors that we are considering are the requests
in flight at load balancer and Load average and memory consumption of cartridge
instance.
Best approach would be to decide the number of instances that will be required
to handle the load in next time interval.
2. Predict the load according to a schedule defined by end user
This aspect will be needed to handle seasonal load expectations.
E.g. High load on Christmas and new year period.
